@TinkerTenor @jb007My experience is that you can move the macOS to either M.2 slot. Just make sure when you install Windows, that you remove any other disks including SATA disks as Windows is known to overwrite the wrong EFI partitions. For the SATA disks, if you are using them, you can just disable the Drives in the BIOS without physically disconnecting them. Hope this helps.
A subtle but noteworthy clarification: Although macOS NVMe can be installed in any M.2 slot, it should be moved to M2P if Windows is also installed in an NVMe SSD. If Windows is installed onto a SATA 2.5" SSD or onto a SATA M.2 SSD then it will operate over the SATA bus instead of PCIe bus, so it won't install its boot loader on the macOS NVMe SSD.
- M.2 slots can accommodate either:
- PCIe SSDs
- SATA SSDs
- SATA ports can only accommodate:
- SATA SSDs
- M2M slot --> Windows PCIe M.2 SSD
- M2P slot --> macOS PCIe M.2 SSD
- Windows SATA M.2 SSD --> M2M or M2P
- macOS PCIe SSD --> M2M or M2P
